D Question 6 1 pts Consider the assembly line below. The two fabrication operations run in parallel, such that each unit only needs to go through one of the fabrication operations. After that, portions of each unit go through both assembly and welding, which occur simultaneously (specifically, 10 components are made for each unit in the fabrication stage-some components are then assembled in the a embly area while others are welded in the welding area). The units are packaged and made ready for shipment in the final stage. The line manager is concerned with the amount of WIP inventory in the system. In an attempt to better understand the actual way the system is operating she collects some data and finds that the average unit is taking 4.25 hours to complete. What is the cycle time efficiency of the system? (choose the NEAREST answer) Fabrication 24 minutes/unit Assembly 7 min/unit Packaging 3 min/unit Welding 6 min/unit Fabrication 24 minutes/unit 15.68% 12.94%
